What is Customer.io?
Customer.io is widening what a journey can express and where its agent can be reached.
Two threads run side by side. The automation engine keeps gaining expressiveness: per-channel rate limits in early August, and now a Wait Until block that accepts multiple delays, time windows, and And/Or/nested condition groups. Separately the AI agent moved into Slack, while messaging reach grew with transactional WhatsApp and support for multiple mobile apps in one workspace.
What is SendPortal?
SendPortal resurfaces with a v4 patch release, its first tag since 2020.
SendPortal's last tagged release before this month was v1.0.3 in July 2020. On October 22 it published v4.0.0.1, which fixes sp:install skipping migrations on fresh installs and a route-caching failure from a duplicate logout route. The changelog link implies a v4.0.0 release just before it, which isn't in the tracked entries.

Customer.io
8.8MKT AUTO
Customer.io is widening what a journey can express and where its agent can be reached.
◆ Current state
Two threads run side by side. The automation engine keeps gaining expressiveness: per-channel rate limits in early August, and now a Wait Until block that accepts multiple delays, time windows, and And/Or/nested condition groups. Separately the AI agent moved into Slack, while messaging reach grew with transactional WhatsApp and support for multiple mobile apps in one workspace.
◆ Where it's heading
The Wait Until change is the clearest read on where the builder is heading: logic that previously needed a chain of wait steps now collapses into one block, which makes journeys shorter and harder to misread. Paired with rate limits and the wait-before-continuing option, timing and pacing are becoming first-class controls rather than things you assemble from primitives. The agent work runs on a separate track, pushing the product into tools people already sit in.
◆ Prediction
Expect the nested And/Or condition model to spread from Wait Until into other branching actions, since the release describes grouping as a property of the path rather than of that single block.
SendPortal
2.5MKT AUTO
SendPortal resurfaces with a v4 patch release, its first tag since 2020.
◆ Current state
SendPortal's last tagged release before this month was v1.0.3 in July 2020. On October 22 it published v4.0.0.1, which fixes sp:install skipping migrations on fresh installs and a route-caching failure from a duplicate logout route. The changelog link implies a v4.0.0 release just before it, which isn't in the tracked entries.
◆ Where it's heading
A major version followed by fixes to the installer suggests the project is active again and new installs are being tested. With two tagged releases six years apart, there's no cadence to read yet.
◆ Prediction
If v4 is a real revival, more point releases should follow within weeks; another long silence would mean v4 was a one-off.
